Why do integers compare equal to booleans?

[Steve Keller]

Why do the integers 0 and 1 compare equal to the boolean values False
and True and all other integers to neither of them?

    $ python3
    Python 3.5.2 (default, Nov 12 2018, 13:43:14)
    [GCC 5.4.0 20160609] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>> 0 == False
    True
    >>> 1 == True
    True
    >>> 2 == False
    False
    >>> 2 == True
    False
    >>> -1 == False
    False
    >>> -1 == True
    False
    >>>

Since these are objects of different types I would expect they cannot
be equal.  I know that 0 means false and != 0 means true in C, C++,
etc. but in Python that surprises me.
